Directed Flow of Λ, Λ3H and Λ4H in Au+Au collisions at √sNN = 3.2, 3.5, 3.9 and 4.5 GeV at RHIC by Han Junyi

“…Heavy-ion collisions from the RHIC beam energy scan phase II (BES-II) provide an unique opportunity to understand these at high baryon densities. In these proceedings, we present a systematic study on energy dependence of the directed flow (v1) for Λ and hyper-nuclei (3ΛH and 4ΛH) from mid-central Au+Au collisions at √sNN = 3.2, 3.5, 3.9 and 4.5 GeV, collected by the STAR experiment with the fixed-target mode during BES-II. …”

Challenges in biomass valorization by olefin metathesis by Del Vecchio, Antonio, Mauduit, Marc

“…In this perspective, olefin metathesis (OM) is one of the best choices to address societal issues, harnessing the conversion of compounds extracted from plants into molecules of interest with a very low carbon footprint. The aim of this article is to highlight and discuss two relevant metathesis processes dedicated to biomass valorization (on the one hand, the transformation of feedstocks resulting from Fischer–Tropsch cuts of wood wastes, and on the other hand, the transformation of unrefined unsaturated fatty esters from sunflower oils) which involve highly efficient and selective ruthenium-based catalysts. …”

Structural Characterisation of Asphaltenes during Residue Hydrotreatment with Light Cycle Oil as an Additive by Yong-Jun Liu, Zhi-Feng Li

“…The findings imply that LCO added to AR during hydrotreating improves the degree of aromatic substitution, the total hydrogen/carbon atomic ratio per average molecule, the distance between aromatic sheets and aliphatic chains, and so forth, by modifying the colloidal nature and microstructure of asphaltene: this is beneficial for the further hydroprocessing of AR. …”

Geochemical and Isotopic Characterisation of Actual Lacustrine Sediments from the Hydrothermal Lake Specchio di Venere, Pantelleria Island (Italy) by Marianna Cangemi, Paolo Madonia, Sergio Bellomo, Ygor Oliveri

“…We collected and analysed 5 sediments cores around the shoreline, determining the mineralogical phases, concentration of major, minor, and trace elements, and the isotopic composition of carbon and oxygen in the carbonate phases. Our findings remarked a general compositional homogeneity in both the vertical and horizontal distribution of mineral phases, with the exception of peculiar geological niches connoted by biological and hydrothermal activities.…”
